摘要： A method for generating a reliability performance model includes developing a reliability prediction machine learning model for predicting reliability performance of a product based on data obtained from manufacturing and testing of the product, and obtaining feature names for the reliability prediction machine learning model and their predictive power values. The feature names may correspond to features from the data obtained from manufacturing and testing of the product. The method may further include extracting a set of feature names corresponding to features having highest predictive power values from the feature names, and generating a reliability performance model using one or more model parameters derived from the set of feature names.

摘要： Computationally efficient and accurate methods of fitting black box simulation data to obtain Linear Parametrically Varying models useful for design of thermal management systems are disclosed. The Linear Parametrically Varying models may be used in dynamic simulations to determine temperatures in thermal systems. A computer-implemented model is run at a plurality of fixed values of the scheduling parameter to obtain output responses to excitations of the input at the fixed values of the scheduling parameter. LTI representations are fit to the output responses, the LTI representations having state-space variables characterized by negative real poles. Coefficient matrices of the LTI representations are updated, and an LPV-ROM representation is generated.

摘要： Data characterizing a fastener and a preload condition applied to the fastener are received in a computer system. A model representing a mechanism coupling a first portion and a second portion of the fastener is created. The first portion and the second portion are located respectively at either end of the fastener along a longitudinal axis of the fastener. The first portion and the second portion are axially displaceable along the axis towards each other via the mechanism and rotatably displaceable about the axis relative to each other via the mechanism. The model includes relative axial displacement and/or relative torsional displacement between the first portion and the second portion corresponding to the preload condition. Physical behaviors of the fastener applied with the preload condition is simulated based on the model.

摘要： Machine assisted systems and methods for use in meshing a periodic pattern of a geometry that represents a physical structure in a simulation of the physical structure are described. The method can include operations: identifying a master region in a periodic pattern of a geometry that represents a physical structure in a simulation of the physical structure that has the periodic pattern; and generating a mesh based on the identified master region, the mesh including a non-planar boundary at a boundary between patterns in the periodic pattern, wherein the master region is only a portion of the representation of the physical structure.

摘要： Systems and methods for deriving material coefficient values from physical measurements of physical objects are described. These physical measurements can provide material test data. In one embodiment of a method described herein, the material test data can be used to calculate a first subset of material coefficients for use in one or more material models from material test data; the method can define a set of optimization parameters and define a set of relationships between a second subset of the material coefficients and the set of optimization parameters such that values of the material coefficients in the second subset of material coefficients can be calculated from the set of optimization parameters, wherein the first subset and the second subset include all of the material coefficients in the one or more material models and the set of optimization parameters have fewer parameters than a total number of coefficients in the first subset and the second subset; then the method can calculate optimum values of the optimization parameters to yield an optimum fit of the one or more models to the material test data, the optimum fit based on optimum material coefficients calculated from the calculated optimum values of the optimization parameters.

摘要： Methods and apparatuses that generate a simulation object for a physical system are described. The simulation object includes a trained computing structure to determine future output data of the physical system in real time. The computing structure is trained with a plurality of input units and one or more output units. The plurality of input units include regular input units to receive input data and output data of the physical system. The output units include one or more regular output units to predict a dynamic rate of change of the input data over a period of time. The input data and output data of the physical system are obtained for training the computing structure. The input data represent a dynamic input excitation to the physical system over the period of time. And the output data represents a dynamic output response of the physical system to the dynamic input excitation over the period of time.

摘要： A system and method of modeling flow of a vasculature in near real-time, is described. A vessel segment of the vasculature is modeled by a reduced order model, and a remainder of the vasculature is modeled by a 0D model. The reduced order model is generated using boundary conditions generated by a 0D model of the entire vasculature. Moreover, the reduced order model of the vessel segment and the 0D model of the remainder of the vasculature can be coupled to simulate flow that can be compared to actual flow measurements to personalize the 0D model of the remainder of the vasculature for a patient. Accordingly, a physician can update parameters of the personalized vascular system model to predict the effects of treatment protocols, including exercise or therapeutic substances, on the patient. Other embodiments are also described and claimed.

摘要： Computer-implemented systems and methods for generating a mesh and conformally connecting the mesh to an existing mesh are provided. The existing mesh is displayed via a graphical user interface (GUI) of a computer-aided design modeling system using a processing system. A polyhedral mesh is generated in an empty space adjacent to the existing mesh using the processing system. The generating of the polyhedral mesh includes (i) defining the empty space as a first surface mesh comprising triangles, quadrilaterals, polygonals, or a mixture thereof, (ii) generating a dual of the first surface mesh to form a second surface mesh, the empty space being enclosed by the second surface mesh, and (iii) filling a gap region between the first and second surface meshes with the polyhedral mesh and conformally connecting the polyhedral mesh to the existing mesh using the processing system.
